* A. (C.) flexuosa (Paykull, 1799)

New records. Taur: Laukesos durpynas, 21 V 1993, leg. R. F., 4³ 3♀, KZM; Šak: Tervydoniai, 27 V 2014, 1³, KZM ; Šven: Snieginio telmologinis draustinis, 5 VI 1998, leg. B. Š., 1, BSC.

Earlier records. This species previously was noted for Lithuania in the Catalogue of Palaearctic Coleoptera ( Nikitsky & Pollock 2008) , but details of this record were unknown.

General distribution. This species is widely distributed in Europe, also noted from Turkey ( Nikitsky & Pollock 2008).

Notes. This species is insufficiently known in Lithuania. It is regarded as an endangered species in Germany ( Schmidl & Bussler 2004).The larvae develop mainly in Inonotus obliquus ( Nikitsky 2002; Nikitsky & Schigel 2004), but also Fomes fomentarius , Fistulina hepatica , Phellinus pini are known host fungi for this species ( Burakowski et al. 1987).

Genus Anisoxya Mulsant, 1856

* A. fuscula (Illiger, 1798)

New records. Kau: Jiesios kraštovaizdžio draustinis, 13 VI 2002 , shaken from the bush branches, leg. A. M., 1♀, AMC.

Earlier records. This species was recorded from Lithuania by Tamutis (2003) in error. The specimen collected in Molėtai district 16 VI 2000 was subsequently identified as Anaspis flava (Linnaeus, 1758) ( Scraptiidae : Anaspidinae ) (KZM).

General distribution. This species is distributed mainly in Central Europe, to the north reaching southern Norway and Sweden ( Nikitsky & Pollock 2008; Konvička 2012). It is very rare in Poland ( Kubisz et al. 2014), and is yet unknown from Latvia and Estonia.

Notes. This is the first actual record of this species in Lithuania. The larvae develop on dead twigs of various deciduous trees, such as Castanea , Corylus , Quercus , Malus , Robinia , and Acer ( Burakowski et al. 1987; Burakowski 2004; Hansen & Sagvolden 1995).

Genus Dircaea Fabricius, 1798

D. australis Fairmaire, 1856

New records. None.

Earlier records. This species was found in Ukmergė district ( Stanionis & Petrikas 2011) (KZM).

General distribution. Previously D. australis was regarded as distributed only in southwestern and southern parts of Europe ( Fairmaire 1856; Burakowski & Pollock 2003). However it was recorded in more recent papers also from southern Sweden ( Lundberg & Gustafsson 1995), Belarus ( Nikitsky & Pollock 2008) and eastern Poland ( Kubisz et al. 2014).

Notes. Two Lithuanian Dircaea specimens (males) were found under the bark of a dead deciduous tree, on 30 VI 2008, by Tadas Petrikas. We studied the morphological characters including structures of genitalia of the specimens and compared them with descriptions of D. quadriguttata (Paykull) and D. australis Fairmaire given by Seidlitz (1898), Kuhnt (1913), Kaszab (1969), Nikitsky (1992) and Burakowski & Pollock (2003). We concluded that our specimens completely fit the description of D. australis , having a compact, almost round yellow spot in the anterior half and almost round (not transverse) yellow spot in posterior half of elytra ( Fig. 2 a ); incomplete lateral bead (indistinct anteriorly) on the pronotum ( Fig. 2 b ), characteristic shapes of aedeagus ( Fig. 2 c ), eighth, and ninth abdominal tergites, and sternites ( Figs 2 d, e, f ). Dircaea australis is regarded as a relict species associated with natural forest ( Kaszab 1969; Schmidl & Bussler 2004; Müller et al. 2005; Eckelt et al. 2018). Larvae develop in white-rotted wood of Fagus and Salix ( Kaszab 1969; Kubisz et al. 2014).
